Embodiments herein relate to in vitro production methods of hematopoietic stem cell (HSC) and hematopoietic stem and progenitor cell (HSPC) that have long-term multilineage hematopoiesis potentials upon in vivo engraftment. The HSC and HSPCs are derived from pluripotent stem cells-derived hemogenic endothelia cells (HE).

Embodiments of the disclosure include methods and compositions for in situ cardiac cell regeneration, including transdifferentiation of cardiac cells to cardiomyocytes. In particular embodiments, in situ cardiac cell regeneration encompasses delivery of p63 shRNA and one or both of Hand2 and myocardin, and in specific embodiments further includes one or more of Gata4, Mef2c, and Tbx5. In specific aspects of the disclosure, adult cardiac fibroblasts are reprogrammed into cardiomyocytes using viral vectors that harbor p63 shRNA and one or both of the transcription factors Hand2 and myocardin.

A method for producing induced photoreceptor cells from an initial cell is provided, the method includes providing one or more transcription factors (TFs) including at least GON4L to the initial cell. In some versions, the initial cell is a human induced pluripotent stem cell (iPSC). In other embodiments the method includes providing the TFs OTX2 and/or NEUROD1 to the initial cell. Cells produced and obtainable by the method are also provided, the use of these cells as a medicament in the treatment of retinopathy, vectors for inducing the photoreceptor cells and combinations of transcription factors intended for this use.

The invention provides a method for influencing the stability of an antibody producing cell, comprising directly or indirectly influencing the amount of BCL6 and/or Blimp 1 expression product within said antibody producing cell. Stable antibody producing cells and cell lines are also provided, as well as methods for producing antibodies using such cells and/or cell lines.

ID Protein targeted cancer immunotherapy. The invention provides a cell-based attenuated live tumor cell vaccine that safely produces broad cellular tumor-specific immunity, protects against tumor formation in prophylactic tumor models, and in combination with the clinically relevant immune modulator s such as antibodies to CTLA-4 or antibodies to PD-L1 can destroy established tumors in mammals.

Methods for identifying compounds that modulate the generation of regulatory T cells (Treg) in vivo and in vitro, i.e., compounds that act on the transcription factors that increase or decrease expression of Foxp3.

Provided herein are isolated neural stem cells. Also provided are methods for treatment of neurodegenerative diseases using suitable preparations comprising the isolated neural stem cells.

Systems and methods (S/M) to detect stress in stem cells are described. The S/M, including modified stem cells, assays and high throughput screens, can be used to identify compounds or other potential stressors that can negatively affect development potential.

The present disclosure relates to the acceleration of hematopoietic compartment reconstitution in a subject in need of hematopoietic stem cell transplantation by administering a composition having a protein transduction domain-MYC (PTD-MYC) fusion protein in combination with hematopoietic stem cell transplantation and to the enhancement of hematopoietic compartment autoreconstitution in a subject in need thereof by administering a composition having a protein transduction domain-MYC (PTD-MYC) fusion protein.

The invention features methods of producing compositions enriched in Tregs and methods for treating immunological disorders using these compositions. The invention also features methods for producing compositions enriched in lymphocytes and depleted of Tregs and the use of these compositions in the treatment of proliferative disorders.
